Challenges

This 4x4 car looks sort
of like a moon buggy. Can you redesign it or add things to it
to make it look more like a monster truck?

The 3-button remote control does not have a way
to go straight backwards in reverse. Note that you cannot use
the dark gray button on the NXT brick because this button always
stops the program. However, by attaching a touch sensor to the
NXT brick with a short wire and modifying the program, you could add a 4th button that will do
whatever you want (go in reverse, honk the horn, or whatever).
Can you figure out how to extend the 3-Button Remoteprogram to add support for
the touch sensor acting as a 4th button?
